5 Hour Energy? Not even 5 minutes!

     If you've been on this planet recently, you can't have failed to notice all those "energy" drinks taking over whole shelves of the supermarkets or convenience stores.  And if you're a reasonably knowledgeable long-distance runner, maybe you've looked at the ingredients and wondered, how can this be?
     The answer:  It can't be.
     Then again, maybe you haven't bothered to read the ingredients lists because you long ago became resigned to the reality that advertising and commerce today are so loaded with lies and deceptions that there's no point in even looking.  But my view is that it's important to look--and think--because dishonest uses of language are becoming more and more common today (listen to the political debates or talk-radio rhetoric), and if we lose credibility in our basic communications, we can very quickly lose control of our whole culture and country.
     So, what does this have to do with running?  Well, a lot.  We runners aren't out there on the roads and trails just for our own pleasure, or at least I hope not.  We've also contributed to a new awakening in the larger population, to the great benefits of physical fitness, vitality, and self-discipline to our families and society.  Half a century ago, John F. Kennedy worried that if Americans become too physically and mentally soft, the country will be in serious danger.  Today, he must be rolling in his grave.
     More particularly, as long-distance runners, we understand the nature of energy in a way our more sedentary citizens (inbcluding most of our politicians) do not.  The physics of energy are the same in our industries as in our bodies, so we hav e some perspectives to share with our leaders that may be quite important for them to begin grasping.  We understand through direct, visceral, experience the difference between an anaerobic sprint, which can last a maximum of no more than 2 minutes or so before you're brought to a gasping halt with your hands on your knees, and a marathon or ultra where you cross the finish line after hours of running, not yet out of breath. 
     Our go-for-broke, growth-at-any-cost modern economy is, as most earth scientists will emphatically attest, what I'd call a sprint economy.  When the scientists say it's "unsustainable," what they mean is that as a civilization, we have the historical equivalent of the sprinter's 2 minutes before we seize up and come to a gasping halt.  For the sake of our children, and our moral legacy to humanity, wouldn't we rather see our leaders become a little more aware of what we endurance athletes now know from gut experience?  In historical time, the sprinter's 2 minutes might translate to no more than a few decades.  (NASA's chief climate scientist, James Hansen, warns that if the planned tar-sands pipeline from Canada to Texas is built, the resulting increment in carbon emissions will mean "game over for the Earth's climate").  But the civilizational equivalent to the endurance runner's hours of sustained effort might translate in historical time to centuries, at least buying time for our species to find a more intelligent adaptation to what is now bound to be a tragically damaged planet.
     So, with what we runners know about energy, what do we make of those booming sales in supermarket energy drinks? 
     What I see, I'm afraid, is an unconscionable reinforcement of the widely held illusion, in our popular culture, that you can get something for nothing.  And that you're a loser if you don't!  Success without practice, reward without work!  If Americans are now quite addicted to the dream of quick shortcuts to whatever we desire (winning the lottery, hitting the jackpot in Vegas, suing for ten million dollars, taking an amazing weight-loss pill), how hard is it to believe that a quick swig of "energy drink" will give you vim and vigor for the next five hours?
     There are a lot of those products out there now, but the one called 5 Hour Energy particularly caught my attention because as an ultrarunner, I'm acutely conscious of just how much energy the human body burns in five hours.  Of course, the amount burned varies considerably with what you're doing, and five hours of running takes a lot more energy than, say, five hours of working at a computer or driving a truck,  Just sleeping, or lying around on a couch for five hours, requires about 250 calories for a 40-year-old, 160-pound man.  But running? More like 4,000 calories.
     Now, look at the label for 5 Hour Energy.  How many calories?  4.  No, I didn't forget any zeroes.  Since calories (or in industry, Calories with a capital "c") are the standard measure of energy fuels, there are two ways to regarding this product.  Either (1) it will give you enough energy to run one-thousandth of five hours, or 18 seconds, or (2) to consume enough of this drink to sustain your pace for 5 hours (instead of drinking legitimate athletic energy drinks), you'd need to chug a thousand of these expensive little bottles in the course of your run.
     OK, I'm being a little deceptive myself, here, because in reality when you're running a marathon or 50k, you don't depend on what you consume en-route for all your energy.  The bulk of your energy is the glycogen you start the race with, stored in your muscles and liver from the dinner you ate the evening before.  But during the race, you do need to replenish at least a few hundred, perhaps a thousand, of those fast-burning calories.  At 4 calories a shot, you won't get very far.
     Maybe it's a measure of how sadly uninformed we are--and how out of touch with our bodies--that these drinks have booming sales.  If you swig one of those things and it feels like the energy is ramped up for a few minutes, it's because the drink is delivering energy you already had in your muscles or blood--sort of like if the milk-man of yore sneaked in your back door and took a quart of milk from your ice-box, then went around to the front door and sold it to you for a dollar.

Good afternoon,
I doubt that ultrarunners would take the 5 hour shot for calories.
Once you are running ultras you really know the basics for hidration and nutrition during the race.
I guess that it maybe useful for ultraruns so long that you get through a night and you may get fallin asleep and caffeine may help to keep it at bay.
Ive seen in long ultras where sometimes people are impacted by being sleepy.
So any kick to avoid that, may help.
what do you think?
